Abstract

Un volant (1) de véhicule, notamment pour véhicules à moteur, comprend autour de sa périphérie (2) plusieurs éléments d'actionnement (5) montés sur la surface circonférentielle intérieure (2a) de la couronne du volant. L'agencement des éléments d'actionnement (5) sur la face intérieure du volant permet d'atteindre facilement les éléments d'actionnement, étant donné que ceux-ci se situent ainsi sur le volant de manière ergonomique, normale et naturelle à la portée du conducteur. En outre, les éléments d'actionnement diffèrent les uns des autres, de sorte que le conducteur peut aisément les reconnaître et les distinguer les uns des autres au toucher. Les éléments d'actionnement peuvent aussi se situer dans des évidements de préhension.
